Hmm... okay. That's something I hadn't imagined in my head about an AST.<br>
That a node can have multiple parents :/<br>
<br>
Just to be clear, getParents(childNode) returns an array of parents<br>
only, right i.e., one indentation level up in -ast-dump output? E.g., an<br>
entry stmt in functiondecl scope has functiondecl as its parent and<br>
*not* translationunitdecl?<br></blockquote><div><br></div><div>Yes.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Okay. I did try using libclang python bindings but the AST it exposes<br>
currently is inferior to what one could get with a libtooling based tool.<br>
<br>
Is AST provided by libclang *proper* (C binding) better than its python<br>
counterpart? I suppose I mean: Is this a rough ordering from rich to<br>
poor AST detail?<br>
